Introduction

SilverStone’s Strider Titanium Series is designed for PC enthusiasts who are looking for a very high efficiency power supply, meeting the top-tier 80 Plus Titanium certification. Starting at 600W and going up to 1500W, the Strider Titanium Series includes six different models. The three lower output models (600W, 700W, and 800W) feature a compact chassis measuring only 150mm deep, while the three high output models (1100W, 1300W and 1500W) forgo the small enclosure and step up to a larger chassis, which measures 180mm deep. Another minor difference is the three lower output models use a 120mm fan while the three higher output models use a 140mm cooling fan.

All of the SilverStone Strider Titanium power supplies incorporate semi-fanless operation (up to 20% load) and come with fully modular cables. Each power supply is built using all Japanese made capacitors and is rated for 24/7 continuous operation at up to 50°C ambient temperature. In this review, we will be taking a detailed look at the Strider Titanium Series ST1300-TI power supply.

Here is what SilverStone has to say about the high efficiency Strider Titanium Series PSUs: “The 80 PLUS Titanium certification represents the pinnacle of power supply efficiency with requirement of at least 90% conversion efficiency even at the very low 10% loading condition.

For SilverStone, achieving the highest efficiency is just one aspect to what makes for a technically advanced power supply. The available power also needs to be condensed into a physical package as small as possible so that users can freely utilize it in any case or system with minimal interference. For the Strider Titanium series power supplies, all models are among the smallest in size for their wattage levels.

As befitting of being in the Strider series, abundant enthusiasts features are included such as all Japanese capacitors, ±3% regulation, powerful single +12V rail, 24/7 continuous power output at 50°, and dual EPS 8pin with multiple PCI-E 8 / 6pin connectors support. For those looking to build the most efficient systems possible with multiple GPUs for gaming, folding, mining, scientific calculations, or machine learning, the 1100W / 1300W / 1500W Strider Titanium series power supplies are definitely the top choices.”

Introduction

Sea Sonic Electronics Co., Ltd has been designing and building PC power supplies since 1981 and they are one of the most highly respected manufacturers in the world. Not only do they market power supplies under their own name but they are the OEM for numerous big name brands. One of their latest power supply offerings is the new PRIME Ultra Titanium Series, which currently includes four models: 650W, 750W, 850W and 1000W. Seasonic has tweaked their current PRIME Titanium lineup to create the new Ultra Series.

The PRIME Ultra Series power supplies incorporate top-notch components and have been designed to deliver the highest level of electrical performance. They feature Titanium level efficiency (80 Plus Organizations highest rating), fully modular cables, and they come backed by a 12-year warranty! We will be taking a detailed look at the new PRIME Ultra 850W Titanium power supply in this review, which Seasonic had shipped to us directly from amazon.com.

The PRIME Ultra Series builds upon the PRIME Titanium platform by delivering extremely tight voltage regulation on the three primary rails (+3.3V, +5V and +12V) and providing superior AC ripple and noise suppression with an extended hold-up time. They feature an new super-quiet, low-speed 135mm cooling fan with a Fluid Dynamic Bearing and come with Seasonic’s premium Hybrid Fan Control that offers fanless operation at low to mid power. The PRIME Ultra Series power supplies also include SATA 3.3 adapters with support for the “power disable” (PWDIS) feature of some newer, high-capacity HDD, a PSU tester, and flexible cables without the little built-in filter capacitors found on previous models.

Enermax have launched a new family of PSUs called MaxTytan, with the 800W model appearing for review on [H]ard|OCP. These PSUs feature Sleemax cabling, each wire is covered in fabric which does look nice but adds bulk to the wires. The cables plus the 80 PLUS Titanium rating add to the price, the MSRP is $200. That hurts the rating [H] provided as the power quality they saw in testing was good, but not great, and is somewhat more expensive than the competition. Drop by for the review, as the PSU provides decent power and a nice look for cases that expose components.

"Enermax pulls out a flagship with its MaxTytan PSU, this one rated at 800 watts. The MaxTytan PSU has some interesting features like its on-demand Dust Free Rotation fan system. It also comes with very "custom" looking SLEEMAX cable covers that wrap every single cable individually like you find in custom rigs. And huge Titanium efficiency!"

SilverStone continues to push the envelope of power density with the release of their new SX800-LTI small form factor power supply. Following close on the heels of the SX700-LPT, the new unit now packs 800 watts into a small chassis. SFX form factor cases and power supplies continue grow in popularity and in market share and as one of the original manufacturers of SFX power supplies, Silverstone Technology Co. is striving to meet customer demand.

SX800-LTI

(SX=SFX Form Factor, 800=800W, L=Lengthened, TI=Titanium certified)

SilverStone has a long-standing reputation for providing a full line of high quality enclosures, power supplies, cooling components, and accessories for PC enthusiasts. With a continued focus on smaller physical size and support for small form-factor enthusiasts, SilverStone added the new SX800-LTI to their SFX form factor series. There are now eight power supplies in the SFX Series, ranging in output capacity from 300W to 800W. The SX800-LTI is the third SilverStone unit to feature a lengthened SFX chassis. The SX800-LTI enclosure is 30mm (1.2”) longer than a standard SFX power supply case, which allows using a quieter 120mm cooling fan rather than the typical 80mm fan used in most SFX power supplies.

In addition to its small size, the SX800-LTI features very high efficiency (80 Plus Titanium certified), all modular flat ribbon-style cables, and provides up to 800W of continuous DC output (850W peak). The SX800-LTI also operates in semi-fanless mode and incorporates a very quiet 120mm cooling fan.

Here is what SilverStone has to say about their new SX800-LTI power supply:

“Since its launch in 2015, the SFX-L form factor has garnered popular recognition and support among enthusiasts with its larger 120mm fan able to achieve better balance of power and quietness in small form factor PCs than what was possible with standard SFX. And as a leader in power supply miniaturization, SilverStone has continued its efforts in advancing the SFX-L forward to reach ever higher limit.

The SX800-LTI not only has unprecedented 800 watts of power output but also has the highest level of 80 PLUS efficiency with a Titanium rating. It includes all features available from top of the line SilverStone PSUs such as flexible flat cables, all Japanese capacitors and advanced semi-fanless capability. For those looking to build the most efficient small form factor systems possible with great quality and power, the SX800-LTI is definitely the top choice.”

We are going to kick-off the New Year on a high-note by taking another look at Seasonic’s PRIME Titanium series power supplies. When we first tested the new PRIME 750W Titanium PSU last summer, we concluded it was the best overall PC power supply we had reviewed to date. So was that just a fluke? Did we get a hand-picked power supply? Or did our review sample truly represent the outstanding performance that a regular user would experience after buying one of the Seasonic PRIME Titanium series power supplies through normal retail channels? Today, we are going to test two more PRIME Titanium PSUs and compare our findings with the original PRIME 750W Titanium power supply test results. This will provide a unique opportunity to compare three different power supplies from the same series to see how consistent their performance really is, which can be a good indicator of quality.

Sea Sonic Electronics Co., Ltd has been designing and building PC power supplies since 1981 and they are one of the most highly respected manufacturers in the world. Not only do they market power supplies under their own Seasonic name but they are the OEM for numerous big name brands.

Seasonic’s new PRIME lineup was introduced earlier this year with the Titanium Series, which currently includes three models: 850W, 750W, and 650W (with more to follow). Additional PRIME models with both Platinum and Gold efficiency certifications are also making their way into retail channels with models ranging from 850W up to 1200W.

The two new power supplies we have in for review are the PRIME 650W and 850W Titanium models. These units also come with all modular cables and are certified to comply with the 80 Plus Titanium efficiency criteria; the highest available. The power supplies are designed to deliver extremely tight voltage regulation on the three primary rails (+3.3V, +5V and +12V) and they provide superior AC ripple and noise suppression with an extended hold-up time. Add in a super-quiet 135mm cooling fan with a Fluid Dynamic Bearing and a 10-year warranty, and you have the makings for an outstanding power supply.

The industries current focus on energy efficiency has made the need for a kilowatt class PSU much less prevalent than a few years back. With current generation components even multi GPU systems can function with a 600W PSU which is why we are seeing so many arriving on the market. This has created a challenge for PSU manufacturers as in order to receive an 80 PLUS certification the PSU must be over 80% efficient even at 10% power draw, over 90% for some of the higher ratings. The Silverstone Strider Titanium 600W PSU came close to meeting those standards in [H]ard|OCP's tests, with some issues in their worst case scenario testing. The PSU also runs about $140 which is somewhat higher than the competition. The news is not all bad, check out their findings in full right here.

"SilverStone has been on a fairly successful ride with its Strider series of computer power supplies. These units tout excellent efficiency levels all while packing this into an unusually tiny footprint perfect for small form factor system builds. The ST60F-TI brings with it a solid build quality, near silent operation, all while being fully modular."

Introduction

SilverStone is a veteran in the PC power supply industry and they continue to offer a full line of enclosures, power supplies, fans, coolers, and PC accessories. They have raised the bar in their Strider power supply series, which now includes three 80 Plus Titanium certified units, the ST60F-TI, ST70F-TI, and ST80F-TI. These three units are billed as being “the world’s smallest 80 Plus Titanium, full-modular ATX power supplies”; with a chassis that is only 150mm (5.9”) deep.

The 80 Plus Titanium efficiency standards were introduced in 2012 and are the most demanding specifications to date. In addition to raising the efficiency requirements at 20%, 50% and 100% loads, the Titanium standard adds a new requirement at 10%. This insures that a Titanium certified power supply will operate with at least 90% efficiency over the full range of loads and deliver up to 94% efficiency at a 50% load.

I’m also happy to report that SilverStone is now providing a 5-year warranty on both the Strider Titanium and Strider Platinum series power supplies; up from their standard 3-year warranty.

SilverStone introduced a 700W SFX-L power supply at CES in January, and with that SX700-LPT PSU now officially released the company has raised the bar again as no less than 800W is coming to the SFX-L form-factor.

SilverStone's SX800-LTI not only offers a massive 800W, but does so with an 80 PLUS Titanium certification (!). The power supply pushes this massive wattage along a single +12V rail, and the SX800-LTI features a fully-modular design for a clean build. An added benefit to the SFX-L form-factor, other than the potential for these powerful designs, is the use of a 120 mm fan, which allows for much quieter operation under load compared to the smaller SFX variant.

We are now approaching full ATX power with these SFX-L PSUs, and indeed the 800-850W range should be all most users would need for even a dual-GPU system (especially as we enter the era of 14-16nm GPUs with their lower power requirements).

Seasonic has announced the PRIME Titanium Series line of power supplies, 80 Plus Titanium certified PSUs that the company says offers superior power regulation with "super-low" ripple noise and extended hold-up times to ensure clean power to your system.

"The culmination of the PRIME Series is the result of Sea Sonic’s close collaboration with graphics card manufacturers and suppliers during product development. Undoubtedly, the electrical performance of the series is unsurpassed by any analog power supply on the market today.

Seasonic PRIME Series power supplies are made with the best quality components, employ an innovative circuit design, and go through rigorous testing to ensure each unit’s amazing load regulation, performance and efficiency. Clean power and prolonged hold-up time (that doubles the current industry standard) are the main characteristics for the ultimate stable performance of the PRIME series power supplies."

Main features of the PRIME Series power supplies from Seasonic:

80 PLUS Titanium or Platinum Certified

Premium Hybrid Fan Control (fanless up to 45 % system load)

Micro Tolerance Load Regulation (0.5 %)

Extended Hold-up Time (above 30 ms)

Ten Year Warranty

The power supplies also offer modular construction and are available in 850W, 750W, and 650W versions. As to pricing and availability, we don't have specifics just yet.
